Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette with a double-net heating wire structure. Background Art

[0002] Electronic cigarettes are products that use electric heating to heat the oil to form vapor aerosol particles for users to inhale. They usually include an oil storage tank, an atomizer core, a control panel, and a microphone sensor. A heating wire is provided in the atomizer core. The oil is absorbed and infiltrated into the heating wire inside the atomizer core. The heating wire heats the oil after being energized. Among the existing electronic cigarettes, there are some electronic cigarette products that use integrated cotton to absorb and store the oil. Since the integrated cotton has better oil locking properties, this type of electronic cigarette usually stores a much larger amount of oil than cartridge-changing electronic cigarettes. Due to the large oil storage capacity, the electronic cigarette is used for a relatively long time. The high frequency and long-term use of the heating wire will cause the heating wire to wear out, which will cause the electric heating effect to decay in the later stage, resulting in a deviation in taste. Utility Model Content

The control board is electrically connected to the transfer pad through a wire, and a control switch is provided on the bottom surface of the control board for controlling the switching of the first heating wire and the second heating wire.

[0005] Furthermore, the atomizer tube is a food-grade stainless steel straight tube, and an oil guide hole is provided on the side wall of the stainless steel straight tube. The first heating wire and the second heating wire are two pieces of metal mesh rolled into a cylindrical shape and arranged coaxially up and down. Oil guide cotton is provided on the outer sleeves of the first heating wire and the second heating wire, and the oil guide cotton is inserted into the stainless steel straight tube.

[0006] Furthermore, the first heating wire and the second heating wire include three pins, a common pin, a first independent pin, and a second independent pin for parallel connection.

[0014] The beneficial effects of the utility model are as follows: the electronic cigarette designed by the technical solution is mainly provided with a first heating wire and a second heating wire double-mesh heating wire connected in parallel. When the double-mesh heating wire is in use, the control switch is used to control the start of a single heating wire, so that the two heating wires can be switched and used alternately to avoid long-term high-frequency operation of only one heating wire, which leads to severe loss and affects performance, thus causing the problem of atomization taste deviation. The two heating wires are switched and used alternately, which is conducive to slowing down the loss and performance attenuation of the heating wire and extending the service life of the heating wire. At the same time, the two heating wires can also work simultaneously at a low frequency. At this time, the air regulating valve can be adjusted to the maximum air intake to meet the atomization taste with large atomization volume and high concentration.

[0015] In addition, the present solution designs that the electrical connection wires of the first heating wire and the second heating wire that are connected in parallel with the control board are transferred through a heating wire pin welding plate, instead of being directly connected to the control board through wires. This is beneficial in ensuring the stability of the electrical connection of the pins of the first heating wire and the second heating wire when assembling the electronic cigarette, and the first heating wire and the second heating wire are not easily damaged by being pulled by the pins.
